Iam literally blown with this amazing battery back up after beta 4. On Beta 3 Screen on time was between 7 hours to 8hours. On Beta 4 iam getting easily 8.5hours to 9 hours screen on time. I have attached the battery usage screen shot. Thank you Samsung. Make sure you guys don't spoil this. Note 20 ultra Iam loving it. 😍😍😍
First thing uninstall Facebook app, download Facebook lite app. Next switch on dark mode. Next turn off nearby device scanning, in sync menu just keep Gmail and contacts sync and turn off other item sync off. In aod.. Keep the options tap to show option. Make sure you check the reviews of any app before downloading as some apps drain the battery. Make sure to keep an eye on which app consume more battery and uninstall and download other equivalent app. Never play in developer options menu.
All my apps are updated. I turn off auto update of apps and when I get notifications if I require to update I will, or else I ignore it. Whatapp is latest version. Yes dual Sim has impact on battery as phone is constantly searching signal. I have single sim.
do u have power saving mode enabled? with less power consuming apps like YouTube we will see better battery. Have u tried with other games or video streaming apps like Netflix? also have u set 120 or 60hz?
